OF POUGHKEEPSIE, NEW YORK.

'31, Y, AND L CONNEGTOR.

Specification of Letters Patent.

Application filed November 27, 1916. Serial No. 133,632.

To all whom it may concern:

Be it known that I, Bonner A. Bncnnn, a citizen of the United States,residing at Poughkeepsie, in the county of Dutchess and State of NewYork, have invented certain new and useful Improvements in T, Y, and LConnectors, of which the following is a specification.

The object of this invention is to provide a device for more eilicientlyconnecting electrical conductors and cables in mechanical constructionwork, particularly in the shapes commonly known as Ts, Ys, Ls, and thelike.

And a further object is to provide in such devices an arrangementwhereby the respective gripping members in being clamped into place binddirectly against each other, or one another, as the case may be, or areseparated only by a washer or other means to lessen the frictiontherebetween.

Further details of the construction and operation of the device arehereinafter fully brought out in the following specification when readin conjunction with the accompanying drawings, in which Figure 1 is anelevational view of a T connector embodying the invention, Fig. 2 is avertical, longitudinal section of the same; Fig. 3 is a vertical,transverse view of the same; Fig. 4 is an elevational view of an l.connector embodying the invention; Fig. 5 is a vertical. longitudinalsectional view of the same; Fig. 6 is an elevational view of a Vconnector embodying the invention; and Fig. 7 is a verticallongiti'idinal sectional view of the same.

Referring particularly to Figs. 1 to 3, a substantially T-shaped hollowcasing 20 is shown as provided with a longitudinally extending bore :21and a transverse intersecting bore each internally threaded and adaptedto receive interchangeable plugs 23, provided in turn with centraloutwardly tapering bores 24 Situated within each of the alined plugs 23is a gripping member comprising a body portion 25 and spaced, tapering,yielding fingers 26, cooperating with the inner tapering bore of therespective adjacent plug to contract said fingers about the baredportion of a conductor or other member 27, as the plug is screwed intoplace. A gripping member 28, similar to that described, but

recessed at 29 in its body portion, is'located within the laterallyprojecting plug, said recess permitting said member to partiallyencircle the others of said members and thus insure a solid uniformcontact between them.

As shown in Fig. 2, a Washer 31 may be placed between said alinedgripping mem-, bers to decrease the friction between them, if they tendto turn with the plugs. The third or laterally projecting grippingmember engages directly against the sides of the others of said members,tending to create a firm unyielding joint, capable of carrying as heavya current as the adjacent wires without any possibility of heating.

The i. connector shown in Figs. 4 and 5 comprises an angular casing 35,having a bore 36 and an angularly extending bore 37, each beinginternally threaded and receiving a centrally bored plug 38, in which islocated a gripping member 39, similar to those hereinbefore described.One of these mem hers is shorter than the other and when in place bearsfirmly against the side of the other of said members, or against a transverse partition, and partially surrounding the latter, if desired. Thus,the conductors 40 or other members are secured together in a very firmengagement, which effectively prevents all heating in the connector, orpossibility of the joint becoming unintentionally loosened.

in the instance of the Y connector, Figs. 6 and 7, a casing 45 isprovided, having three angularly positioned bores 46, either of the sameor of diiferent diameters, in the outer ends of which are normallyscrewed plugs 47, having central tapering bores 48, in which aresituated similar gripping members 49. Said last-named members preferablyhave positioned between them bushings, two of which 50 are beveled at51, while the third 52 has converging surfaces 53 against which thebeveled surfaces of the 'other bushings are forced, as the respectiveplugs are screwed into place.

Having thus described my invention, what I claim and desire to protectby Letters Patentof the United States is A connector, comprising acasing having a bore, an outwardly tapering gripping member within saidbore, a contracting member having a tapered bore and adapted to bescrewed in said casing and contract the tapered end portion of saidgripping mem- Patented July 6, 1920.

ber extending into said last-named bore and a second bore Within saidcasing opening into said first bore, the axis of said casing bores beingangularly disposed With respect to each other, an outwardly taperinggripping member Within said last-named bore, and a second contractingmember having a I tapered bore and adapted to be screwed upon saidcasing and contract the end portion of 10 said second gripping memberextending into the bore of said second member by forcing In testimonywhereof I have afiixed my 15 signature in presence of two Witnesses.
